four stroke engine gives power in two rotation of crank.But two stroke engine gives power in one rotation of the crank.
four stroke engine does not have transfer port,but two stroke engine have that. Two stroke engine's working fuel is petrol,but four stroke engine may suit in all fuels such as petrol,diesal&gas.

Answer / stevolandis

A- four stroke has oil in the bottom of the cylinder, below
the piston, gas mixture= on top. oil doesn.t combust cause
it isn't in the upper cylinder, where the spark takes
place. 2-stroke= definatly lighter than a 4s. 2s will rev
much higher than a 4s- a 2s is a performance engine- built
for speed.

Answer / suneetha

sorry guys..i thought that is difference b/n SI and CI
engines..
and now for this question it is..
a four stroke engine does't consume mobil oil in the fuel
where as in two stroke engine..because of one power stroke
in two revolutions..

Answer / suneetha

A four stroke engine is lighter than a two stroke
engine.because
2 stroke engine should have high compression ratio when
compared to 4 stroke engine right..then 2 stroke engine
should have a huge construction to get those high
compression ratio...
